An elevator system having a controller configured for: receiving a communication from the mobile device for a passenger, the communication including first data, wherein the first data is position data obtained by the mobile device executing a multilateration (MLAT) process with one or more proximately located telecommunication devices, rendering a first determination, from the first data, that the mobile device is proximate a first distance from the lobby, rendering a second determination, from the first determination, arrive at the lobby proximate a first time, and transmitting a communication to an elevator instructing the elevator to arrive at the lobby proximate the first time to provide elevator service.

The present invention relates to automatic elevator call control, and belongs to the field of elevator intelligent control technologies. An automatic elevator call system provided in the present invention calculates duration information from the moment when the personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again, and when the duration information is less than or equal to a preset time threshold, causes the personal mobile terminal to be incapable of automatically sending an elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again. The present invention can effectively avoid invalid or abnormal elevator call request operations, and the elevator system achieves high running efficiency.

The invention comprises a method and a system for conveying a mobile robot in an elevator involving the monitoring of elevator operating components and of persons surrounding the elevator and operating the elevator by selecting a floor to which the mobile robot is to move. In one aspect an inertial sensor is used to learn or determine the number of floors. The robot may also have methods implemented to assess the floor space inside the elevator or to position itself in front of the elevator in such a way that it can, for example, monitor the operation of elevator operating components without being perceived as an obstacle from the elevator users' perspective.

An illustrative example embodiment of an elevator system includes a destination entry device configured to allow a passenger to indicate an intended destination prior to entering an elevator car and at least one detector configured to detect a proximity between the passenger and at least one other individual that has not indicated an intended destination. A controller is configured to determine whether the detected proximity between the passenger and the at least one other individual satisfies at least one criterion indicating that the at least one other individual likely is associated with the passenger, will board an elevator car with the passenger, and will travel to the intended destination with the passenger. The controller is configured to assign an elevator car to carry the passenger and the at least one other individual to the intended destination when the detected proximity satisfies the at least one criterion.

The invention refers to an arrangement for the allocation of destination calls in an elevator system with at least two elevators, comprising a wireless transmitter device connected with an allocation control of the elevator system. The transmitter device interacts within a certain mutual distance with a wireless ID device carried by a passenger, which ID device is configured to transmit to the transmitter device an ID which is linked with a special transportation service in the elevator system. The elevator system comprises a memory with correlated operation parameters of the elevators which are linked to the particular special transportation service request of the ID device, whereby the ID device is configured to transmit ID data and/or a call with a departure floor and destination floor to the allocation control. The transmitter device is located within a transmitter accommodation space located at least in the vicinity of an elevator, whereby the transmitter device is located in the vicinity of a tag carrying a symbol correlated to the special transportation service.

The present invention relates to tracking of a passenger flow in an elevator car. A passenger flow tracking system for an elevator car according to the present invention includes: a first Bluetooth module installed in the elevator car, the first Bluetooth module being configured to broadcast a first Bluetooth signal that can substantially cover the interior of the elevator car and receive a response fed back by a personal mobile terminal carried by a passenger inside the elevator car; and a passenger flow determining unit configured to at least determine, based on a change in the received response, that the passenger leaves and/or enters the elevator car.

According to an aspect, there is provided a method and an apparatus for transmitting an elevator call. In the solution, a predetermined triggering event associated with a status of a vehicle is identified and transmission of the elevator call is caused based on the predetermined triggering event associated with the status of the vehicle.

An access control system for an elevator system includes a gate device allowing access for users via the gate device, at least one imaging device for obtaining image data, at least one sensor device for obtaining sensor data, at least one indication device, and a control unit. The control unit is configured to: receive the image data from the at least one imaging device, detect a user approaching the gate device based on the received image data, obtain destination floor information including at least two destination floors, control the at least one indication device to generate a first visual indication including the at least two destination floors, and detect a destination floor selected by the user from among the at least two destination floors based on sensor data received from the at least one sensor device. An elevator system includes an access control system and to a method for controlling an access control system is disclosed.

An indication system for generating an indication includes at least one indication device, at least one detection device configured to monitor at least one area inside a building to provide monitoring data, and a control unit. The control unit is configured to: detect based on the monitoring data obtained from the at least one detection device at least one predefined gesture of an identified user for which an elevator car (A-D) has been allocated, and control the at least one indication device to generate a visual indication on a floor of the building in a vicinity of the identified user in response to the detection of the at least one predefined gesture of the identified user. A method for generating an indication is also disclosed.

Provided is a server device with which it is possible to suitably discern whether a user uses an elevator. The server device comprises a first generation unit, a second generation unit, and an output unit. The first generation unit analyzes image data obtained from at least one or more camera devices and generates elevator information pertaining to the usage state of an elevator The second generation unit generates, on the basis of at least the generated elevator information, during-movement reference information that is referred to when the user moves. The output unit outputs the generated during-movement reference information to signage.
